General Description

TDC-GP30 is the next step in ultrasonic flow metering. It drastically simplifies the design of ultrasonic heat and water meters and is the necessary step for compact energy-saving ultrasonic water meters. The ultra-low current capabilities allow the use of standard 2/3 AA or AA lithium thionyl chloride batteries at 6-8 Hz measuring frequency even in the water meter version. The TDC-GP30 is a system on chip approach that allows you to perform all measurement tasks in one IC.

This product suits for the following applications:

  • Ultrasonic water meters
  • Ultrasonic heat meters
  • Ultrasonic gas meters
  • Industrial flow indicators
